Cartridge mechanical seal manufacturer and supplier right now: What is an O-ring? O-ring is an annular ring designed to prevent the passage of liquids or gases. It is one of the simplest precision mechanical parts ever produced and continues to be one of the most widely used sealing products. O-rings can be made of plastic or metal, but as far as our blog is concerned, we will only focus on rubber (or elastomer) O-ring design. O-rings (also called “torus”) work in concert with the glands in which they are installed. The gland is usually cut from the metal hardware and sealed with the O-ring. The gland and O-ring must be designed together to ensure optimal performance. Read even more details at cartridge type mechanical seal.
In China, many factories use viking gear pumps, especially viking gear pump are widely used in resin industry, Paint industry, Lubricating oil industry, High viscosity working condition, so viking pump seal is really a nice demand in market. not only in China, but also in other oversea countries. In China market, the most popular viking gear pump item include: K227A(8088730103), LL724, LQ224A,LQ724A(8088840089), QS4124A SER. 12133804, even some agent of viking pump buy cartridge mechanical seal from our factory.
We use carbon and SIC as the raw materials for manufacturing the rotary and stationary seal parts. Due to the characteristics of the SIC, the product is endowed with the performance of stable chemical properties, low thermal expansion coefficient and good wear resistance. Besides that, the product is equipped with strong cast iron which gives it long service life. As for the secondary seal, we use EPDM to help the product gain the advantages of weather resistance, ozone resistance, heat resistance, acid and alkali resistance.
Take the mechanical seals – the most commonly used and popular products now – as the example: It is also known as a face seal, which is a rotary machine shaft seal device that can avoid the leakage of the fluid. It is widely used for the rotation of the shaft seal, for pumps, kettle, compressor, and other similar equipment. There are a lot of materials for manufacturing the mechanical seals, including rubber, stainless steel, PTFE, carbon, ceramic, Sic and TC.
We provide CAD drawings for customers so that they can see the inner parts and external design of the seals. Or if customers have their design concept or already get their product drawings, it is also practicable in Lepu Seal. Sample production and delivery: After getting confirmation from customers, Lepu Seal will make the exact sample based on the drawing. Having finished the sample, we will carry out strict QC procedure to test the sample and then deliver it.
For better satisfying the needs of customers, the product can be provided with different shaft sizes ranging from 24mm to 100mm. In Lepu Seal, Alfa Laval mechanical seal LPSRU3 is a professionally designed mechanical seal replacement for Alfa Laval pump SRU3. Super light screws are designed on the seal ring, which both guarantees the easy operation and strong structure. Each product is designed with precise dimension ranging from 20mm to 45mm, which can satisfy the different needs of customers. Read even more details at https://www.lepuseal.com/.
The following aspects are going to affect the durability of your shaft seals. The aspect of the lubricant that is utilized. A lubricant in simple terms is a fluid that is supposed to soften a surface area that is rough. It is quite surprising to find out that it is one of the factors that will reduce the life span of your shaft seals. One fact that is known is that the interaction between the seal material and the lubricant is unavoidable; they must work together for good operations of the shaft seal. During the shaft seals operations, both the seal edge and the lubricant are highly visible to the unbearable thermal and mechanical conditions. The exposure is not quite good for your shaft seal since it makes them do more of the work than it is supposed to do. The exposure also allows for the clipping of the lubricating film and passing of oxygen which is otherwise not needed during operations.
John Crane mechanical seal is one of the most popular in the seals industry. Designed with a drive band and drive notches, this type of mechanical seal has a strong ability to absorb the force of the running torque. Its bi-directional and robust force of the seal face helps eliminate the pressure on the bellow. Its innovative bellows design is pressure-supported and will not crease or fold under high pressure. Besides that, the full convolution elastomeric bellows seal is designed to fit into confined spaces. Equipped with the function of automatic adjustment, it can be tolerant of the abnormal shaft-end play and run-out. There will be no clogging when this product is used and the single-coil spring keeps seal faces closed and properly tracking during all phases of operation. Under upset conditions, the positive drive through interlocking tangs will not go wrong.
